I don't quite understand LateX yet. Does it do calculations for me?

For calculation with LaTeX could be useful a CalcTeX package.

I supposed that for calculations could be helpful a CalcTeX package. This package used a TeX and/or LaTeX standard input file with defined values and relations and generated TeX/LaTeX output file with calculated values. Is possible calculation with units.

For calculations with LaTeX and TeX I'm using a CalcTeX package, this package, documentations and examples are available on http://sg.bzip.pl/CalcTeX/en.html. I'm author of this package and let me know if you have any problems. I hope CalcTeX would be supportive for you.
